Curtain rail

Abstract

A curtain rail includes a tube and a decoration bar. A rail groove allowing hooks arranged therein is defined on a side of the tube. The rail groove extends along a longitudinal direction of the tube, and a latch structure is protruded on another side of the tube. At least an assembling groove corresponding to the latch structure is defined on a lateral surface of the decoration bar and the assembling groove extends along a longitudinal direction of the decoration bar. The latch structure is detachably inserted in the assembling groove and the decoration bar is thereby detachably assembled with tube. The decoration bar is fixed on the tube by embedding the latch structure into the decoration bar, and the tube thereby could be completely shielded by the decoration bar.

What is claimed is: 
     
         1 . A curtain rail, for slidably arranging a plurality of hooks thereon, the curtain rail comprising:
 a tube, a rail groove for arranging the hooks therein being defined on a side of the tube and the rail groove being extend along a longitudinal direction of the tube, a latch structure being protruded on another side of the tube; and   a decoration bar, at least one assembling groove corresponding to the latch structure being defined on a lateral surface of the decoration bar and the at least one assembling groove being extending along a longitudinal direction of the decoration bar;   wherein the latch structure is detachably inserted in the assembling groove and the decoration bar is thereby detachably assembled with the tube.   
     
     
         2 . The curtain rail according to  claim 1 , wherein the assembling groove is a dovetail groove and the latch structure is a dovetail latch corresponding to the dovetail groove. 
     
     
         3 . The curtain rail according to  claim 1 , wherein the latch structure comprises a couple of inclined plates arranged at interval, the couple of inclined plates are divergently protruding from the tube, and the couple of inclined plates are extending on the tube along the longitudinal direction of the tube and parallel with each other. 
     
     
         4 . The curtain rail according to  claim 3 , wherein a couple of assembling grooves are defined on the decoration bar, and each inclined plate is detachably inserted in the corresponding assembling groove. 
     
     
         5 . The curtain rail according to  claim 1 , wherein an installing plane extending along the longitudinal direction of the tube is formed on the tube, and the latch structure is protruded on the installing plane. 
     
     
         6 . The curtain rail according to  claim 5 , wherein the installing plane is shielded by the decoration bar. 
     
     
         7 . The curtain rail according to  claim 5 , wherein the decoration bar extends beyond a circumference of the installing plane.
